DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be used by laying it back and forth, right and left, and therefore has a predetermined size and shape, and has a tray structure capable of growing plants. In the present invention, the tray structure means a shallow container-like structure, which is basically impermeable to water and has root protection. For example, concrete products and resin molded products are suitable as the tray for greening of the present invention.

[0006] Therefore, this tray is a shallow container having a bottom plate and a frame surrounding the bottom, and a medium material can be placed inside the bottom plate and the frame. It goes without saying that the medium material must be a material suitable for growing plants, but the material, shape and structure can be freely selected.

[0007] It is necessary that the bottom plate portion of the tray has an uneven structure composed of a large number of concave portions and convex portions. The concave portion is a portion for storing water to the last, and the upper surface of the convex portion is a portion for defining a water level. This structure appears not only in the inside of the container but also on the lower surface of the tray as irregularities, and a gap is formed between the tray and the installation surface.

[0008] A drainage port for draining excess water and a fixing means for fixing a culture medium provided inside are provided in the concave portion or the convex portion. It is preferable that the water drainage port is provided on the upper surface of the convex portion, since excess water can be discharged while keeping the water storage portion and the air layer portion below the water drainage port. The fixing means is to mechanically combine with the medium material to obtain a fixed state,
For example, it is desirable to have a structure that pierces the medium material, such as Kenzan used for ikebana. Further, the fixing means may be provided at a portion other than the convex portion, for example, within the concave portion, or at an intermediate portion which is neither the concave portion nor the convex portion.

The trays of the present invention are used by laying them back and forth, right and left, and at this time, adjacent trays can be connected by a joint. Small holes or small projections are provided at the corners of the bottom plate as attachment portions for the joint.
A corner or the like is a person who has approached outside such as a corner or an edge. The joint will thus have a plurality of similar connections mating with the small holes or small projections.
